Description

Technical Field

[0001] The utility model relates to a paint bucket labeling system. Background Art

[0002] A Chinese patent with application number 201921061416.9 discloses a paint bucket labeling system, which can clamp the paint bucket body through four rotating rollers and drive the bucket body to rotate, and then cooperate with a labeling mechanism to label the surface of the bucket body.

[0003] The patented paint bucket labeling system includes: a chain plate conveyor belt for conveying paint buckets, a barrel angle adjustment mechanism disposed above the conveyor belt and used to adjust the angle of the paint bucket body, and a labeling mechanism disposed above the conveyor belt and used to affix label paper to the paint bucket body;

[0004] The barrel angle adjustment mechanism comprises: a lifting plate arranged directly above the conveyor belt, a frame arranged directly above the lifting plate, a lifting unit arranged on the frame and used to drive the lifting plate to lift and lower, a vertical rotating roller penetrating the lifting plate, a clamping driving unit used to drive the rotating roller to clamp the paint barrel, and a rotating unit used to drive at least one rotating roller to rotate;

[0005] The lifting plate is provided with: two strip-shaped holes respectively arranged at the front and rear ends of the lifting plate and extending in the left-right direction; the two strip-shaped holes include: a front strip-shaped hole located at the front end of the lifting plate, and a rear strip-shaped hole located at the rear end of the lifting plate;

[0006] There are four rotating rollers, and the four rotating rollers are arranged in a square shape; the four rotating rollers include: a front left rotating roller and a front right rotating roller penetrating the front strip-shaped hole and arranged at the left and right ends of the front strip-shaped hole, and a rear left rotating roller and a rear right rotating roller penetrating the rear strip-shaped hole and arranged at the left and right ends of the rear strip-shaped hole;

[0007] The clamping drive unit comprises: two polished rods respectively arranged at the front and rear ends of the lifting plate and extending in the left and right directions, two sliders sleeved on the polished rods and respectively arranged at the left and right ends of the lifting plate, and a bidirectional cylinder arranged on the lifting plate and used to drive the two sliders to move closer to or away from each other; the two sliders comprise: a left slider arranged at the left end of the lifting plate and rotatably connected to the front left rotating roller and the rear left rotating roller, and a right slider arranged at the right end of the lifting plate and rotatably connected to the front right rotating roller and the rear right rotating roller;

[0008] The lifting unit comprises: four vertical guide rods arranged on the frame and passing through the four corners of the lifting plate, and a lifting cylinder arranged on the frame and having an output end fixedly connected to the lifting plate;

[0009] The rotating unit comprises: a servo motor configured for at least one rotating roller.

[0010] The working principle of this patented paint bucket labeling system includes:

[0011] The chain plate conveyor belt conveys the paint bucket. When the paint bucket is conveyed to the bottom of the lifting plate, the chain plate conveyor belt stops. At this time, the paint bucket is facing the labeling mechanism.

[0012] Then the lifting unit (lifting cylinder) drives the lifting plate to drive the four rotating rollers to move downward, so that the four rotating rollers surround the paint bucket; then the bidirectional cylinder drives the left slider and the right slider to move closer to each other, so that the four rotating rollers move synchronously in pairs (the front left rotating roller and the rear left rotating roller move synchronously to the right, and the front right rotating roller and the rear right rotating roller move synchronously to the left) to clamp the paint bucket;

[0013] Then the rotating unit (servo motor) drives the rotating roller to drive the paint bucket to rotate around its own axis; first adjust the angle of the paint bucket body to the set angle (rotate the QR code on the bucket body to just below the labeling roller of the labeling mechanism), and then make the paint bucket body continue to rotate in coordination with the labeling mechanism, and the labeling mechanism sticks the label paper to the bucket body during the barrel body rotation;

[0014] After labeling is completed, the bidirectional cylinder drives the left and right sliders to move away from each other, so that the four rotating rollers move synchronously in pairs (the front left rotating roller and the rear left rotating roller move synchronously to the left, and the front right rotating roller and the rear right rotating roller move synchronously to the right) to separate from the paint bucket; then the lifting unit (lifting cylinder) drives the lifting plate to drive the four rotating rollers to move upward, so that the four rotating rollers move to the top of the paint bucket;

[0015] The chain conveyor then continues to transport the finished paint buckets.

[0016] Although the paint bucket labeling system of the patent can clamp the paint bucket body through four rotating rollers and drive the bucket body to rotate, and then cooperate with the labeling mechanism to label the barrel body surface; but when clamping the paint bucket body, the four rotating rollers move synchronously in pairs (the front left rotating roller and the rear left rotating roller move synchronously to the right, and the front right rotating roller and the rear right rotating roller move synchronously to the left), and the spacing between the front and rear rotating rollers in the front-to-back direction cannot be adjusted (the spacing between the front left rotating roller and the rear left rotating roller cannot be adjusted, and the spacing between the front right rotating roller and the rear right rotating roller cannot be adjusted), so the size of the paint bucket that the four rotating rollers are suitable for is limited to a certain extent; if the outer diameter specification of the paint bucket body is not compatible with the spacing between the front and rear rotating rollers in the front-to-back direction, the four rotating rollers may not be able to stably clamp the paint bucket body, and may not be able to drive the barrel body to rotate stably, and may not be able to cooperate with the labeling mechanism to accurately label the barrel body surface, resulting in poor labeling.

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0029] The specific technical solutions implemented in this utility model are as follows:

[0030] like Figure 1 As shown, a paint bucket labeling system includes: a chain plate conveyor belt for conveying paint buckets, a barrel angle adjustment mechanism arranged above the conveyor belt and used to adjust the barrel angle of the paint bucket, and a labeling mechanism arranged above the conveyor belt and used to attach label paper to the barrel body of the paint bucket;

[0031] The barrel angle adjustment mechanism comprises: a lifting plate 2 arranged directly above the conveyor belt, a frame arranged directly above the lifting plate 2, a lifting unit arranged on the frame and used to drive the lifting plate 2 to lift and lower, a vertical rotating roller 3 passing through the lifting plate 2, a clamping driving unit used to drive the rotating roller 3 to clamp the paint bucket, and a rotating unit 12 used to drive at least one rotating roller 3 to rotate;

[0032] The lifting plate 2 is provided with: three strip holes 7 arranged in a Y shape and extending toward the center of the lifting plate 2;

[0033] There are three rotating rollers 3, and the three rotating rollers 3 correspond to the three strip holes 7 one by one, and the rotating rollers 3 pass through the corresponding strip holes 7; the three rotating rollers 3 are arranged in an equilateral triangle, and the center of the equilateral triangle coincides with the center of the lifting plate 2;

[0034] There are three clamping drive units, which correspond to the rotating rollers 3 one by one. The clamping drive units are used to drive the corresponding rotating rollers 3 to approach or move away from the center of the lifting plate 2 along the extending direction of the corresponding strip holes 7;

[0035] The clamping drive unit comprises: a slider 5 slidably disposed on the top surface of the lifting plate 2 and rotatably connected to the corresponding rotating roller 3, a pair of slide rails 23 disposed on both sides of the corresponding strip hole 7, extending in the same direction as the corresponding strip hole 7 and slidably cooperating with the slider 5, and a telescopic cylinder 24 disposed outside the corresponding strip hole 7 and driving the slider 5 to approach or move away from the center of the lifting plate 2 along the extending direction of the corresponding strip hole 7;

[0036] The lifting unit comprises: four vertical guide rods 9 arranged on the frame and passing through the four corners of the lifting plate 2, and a lifting cylinder 8 arranged on the frame and having an output end fixedly connected to the lifting plate 2;

[0037] The rotating unit 12 includes: a servo motor configured for at least one rotating roller 3 .

[0038] The working principle of the paint bucket labeling system of this utility model includes:

[0039] The chain plate conveyor belt conveys the paint bucket. When the paint bucket is conveyed to the bottom of the lifting plate 2, the chain plate conveyor belt pauses. At this time, the paint bucket is facing the labeling mechanism.

[0040] Then the lifting unit (lifting cylinder 8) drives the lifting plate 2 to drive the three rotating rollers 3 to move downward, so that the three rotating rollers 3 surround the paint bucket; then the three telescopic cylinders 24 respectively drive the three sliders 5 to synchronously approach the center of the lifting plate 2 along the extension direction of the corresponding strip holes 7, so that the three rotating rollers 3 clamp the paint bucket;

[0041] Then the rotating unit 12 (servo motor) drives the rotating roller 3 to drive the paint bucket to rotate around its own axis; first adjust the angle of the paint bucket body to the set angle (rotate the QR code on the bucket body to just below the labeling roller of the labeling mechanism), and then make the paint bucket body continue to rotate in coordination with the labeling mechanism, and the labeling mechanism sticks the label paper to the bucket body during the barrel body rotation process;

[0042] After labeling is completed, the three telescopic cylinders 24 respectively drive the three sliders 5 to synchronously move away from the center of the lifting plate 2 along the extension direction of the corresponding strip holes 7, so that the three rotating rollers 3 are separated from the paint bucket; then the lifting unit (lifting cylinder 8) drives the lifting plate 2 to drive the three rotating rollers 3 to move upward, so that the three rotating rollers 3 move to the top of the paint bucket;

[0043] The chain conveyor then continues to transport the finished paint buckets.

[0044] As can be seen from the above, the paint bucket labeling system of the present invention can clamp the paint bucket body through three rotating rollers 3 and drive the bucket body to rotate, and then cooperate with the labeling mechanism to label the surface of the bucket body; and compared with the method of using four rotating rollers to move synchronously in pairs to clamp the paint bucket body, the present invention uses three rotating rollers 3 to synchronously approach the center of the lifting plate 2 to clamp the paint bucket body, which can adapt to paint bucket bodies with more outer diameter specifications, can clamp the paint bucket body more stably, and thus make the rotation of the bucket body more stable, so that the labeling mechanism can label the barrel surface more accurately, and can improve the labeling effect.

[0045] The utility model is a partial improvement on the paint bucket labeling system disclosed in the Chinese patent application number 201921061416.9, mainly changing the method of clamping the paint bucket body by using four rotating rollers moving synchronously in pairs to clamping the paint bucket body by using three rotating rollers 3 synchronously approaching the center of the lifting plate 2. The utility model does not improve other parts of the patent. The other parts of the paint bucket labeling system can refer to the specification of the patent and will not be repeated here.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
